Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484648, here are decompositions:

31 + 31484617 = 31484648
79 + 31484569 = 31484648
199 + 31484449 = 31484648
271 + 31484377 = 31484648
331 + 31484317 = 31484648
367 + 31484281 = 31484648
409 + 31484239 = 31484648
439 + 31484209 = 31484648

Showing the first eight; more decompositions exist.
